Suppose that $P_1=2\mathrm{kN}$ and $P_2=1.5\mathrm{kN}$. (Figure 1) Determine the force in member $GF$ of the roof truss. Express your answer to three significant figures and include the appropriate units. Enter negative value in the case of compression and positive value in the case of tension. Part $\mathrm{B}$ Determine the force in member $\mathrm{CF}$ of the roof thus Express your answer to three significant figures and include the appropriate units. Enter negative value in the case of cornpression and positive value in the case of tension. Part c Determine the force in member $CD$ of the roof truss. Express your answer to three significant figures and include the appropriate units. Enter negative value in the case of compression and positive value in the case of tension.
